A SAR-Assisted DC-Coupled Chopper-Stabilized 20μs-Artifact-Recovery $\Delta \Sigma$ ADC for Simultaneous Neural Recording and Stimulation
Driven by the high efficacy of electrical neuro-stimulation in treatment of various neurological disorders, optimizing stimulation parameters for each specific patient has become a highly sought goal [1]. This optimization requires recording neuronal activity (10μV-1 mV) during and shortly after stimulation, when large (e.g.,>100mV) stimulation artifacts are present at all recording electrodes. Thus, a very large (>80dB) dynamic range (DR) is needed for the neural recording front-end, which cannot be achieved using conventional amplifiers.
